Hi everybody,
Currently I'm in the process of developing an R library, where I make
use of pointLabel in the maptools package. I've defined the
dependency on package maptools via the DESCRIPTION file in the root
directory of my library.
Since the loading of package maptools issues a

Hi Guys
I have defined a generic function, for which one of the arguments has a
default:
setGeneric( getFwdRate,
function(.Object, tenorFrom, tenorTo=tenorFrom)
standardGeneric(getFwdRate)
)
Then I have defined a method which also has a default:
setMethod( getFwdRate,

The problem here is that the primitive for `$` does not use standard R
evaluation on its second argument, so when it is selected as the next method
the call is effectively x$name regardless of the original call.
If possible, I would avoid such cascaded
The survexp function can fail when called from another function. The why of
this has me baffled, however.
Here is a simple test case, using a very stripped down version of survexp:
survexp.test - function(formula, data,
weights, subset, na.action, rmap,

No, I have not lost an environment. I manufactured a formula which

Hi Terry,
This may not really be a complete answer, but there seems to be a
difference in eval'ing an expression compared to eval'ing a call (even
though both are documented in the help page for eval as working just fine).
If you insert the line
print(eval(expression(zed),

Kevin,
The answer came from Gabor -- the model.frame function has a
non-standard evaluation, in that it uses the enviromnent attached to the
formula as the enclosure for looking up variable names.
This is clearly documented and I somehow missed it when reading the
page. So reading deficit is

I'm still puzzled by recover though.
It looks like a buglet. You get to the right frame (try ls()) but the
called from message is off by four frames.
E.g.
Selection: 1
Called from: model.frame(formula = zed ~ 1+age+sex+year, data = mydata)
I can see this has been addressed, thanks!
I found a couple more issues with installed.packages().
The values returned in the Archs column don't seem to really make
sense on Unix:
installed.packages()[1:5, c(Version, Archs, Built)]

I notice that a fix for this issue was checked in. Thanks, much appreciated!
But it still seems broken on Windows. Given the same ruby script, and this R

cmd - c:/ruby192/bin/ruby
